    Wow! What a terrific success! Great speakers, lots of really interested people in attendance. The Cloud Center was a really good venue, with personal attention given by their leaders (Dave Nielsen and Scott Strobele). The best thing of all was the terrific opportunity for the attendees to hear from very knowledgeable people and be given an amazing environment with real life, big data, to practice on. Congratulations to the ACM council and volunteers: Tricia Hoffman, Greg Makowski, Vera Klimkovsky, Xavier Palathingal, Greg Weinstein, Steve Lazarus, Liz Fraley, Bill Bruns, and all the rest! Thanks to Red Rock in MV for coffee; Microsoft for great box lunches from Panera Bread; Best Buy for supplying 2 years of real life data; all our speakers - on and on! Another great success by the SF Bay ACM ! Hope to see you all at our 5th yearly Data Mining conference in October (see
